This service call initializes the fixed-size memory pool indicated by mpfid. If tasks are enqueued in a memory block wait-
ing queue, all of the tasks enqueued in the memory block waiting queue are released from WAITING state. Furthermore,
the error code EV_RST is returned to the tasks that have been released from WAITING state.
This service call can be issued only from task context. It cannot be issued from non-task context.
